IMPROVEMENT IN HORSE-POWERS.

Specification forming part of Letters Patent N0.129,627, dated July 16, 1872.

Specification describing anew and Improved Horse-Power, invented by SAMUEL E. TooLY, of Delphi, in the county of Onondaga and State of New York.

My invention consists of a horse-power for driving crosscut and circular sawing machines and thrashing and other machinery, in which there is a simple and economical duplicate arran gement for working two crosscut saws and a shifting-gear for connecting and disconnecting said saws alternately, whereby one may be kept at work while the other is resting and the log is being adjusted, so that the team and attendant may be employed the whole time, and the stopping and starting necessary when only one saw is used may be avoided.

Figure l is a plan view of my improved apparatus, and Fig. 2 is a side elevation.

Similar letters of reference indicate correspondin g parts.

A is a large bevel driving-wheel on a short vertical shaft, B, mounted on a suitable plat form, D, and having one or more sweeps, E, projecting from the upper end for hitching the horses to. E, F, and G represent three transmitting-shafts, radiating from the under side of said driving-wheel on three sides, and gearing with it by pinions H. The shafts E and F, which are in the same right line, are arranged for sliding endwise to gear with the driving-wheel or not, as required; and they are provided with shifting-levers I, arranged parallel with each other, so that when both are moved in one direction one shaft will be connected. with said driving-wheel and the other will be disconnected; and, for moving them simultaneously, and by one and the same operation, they are connected together by a cord, K, as shown, and said cord is extended from side around a guide-pulley, L, to a post, M, near the place where one of the cut-off saws N is arranged, and from the other lever it is extended around guide-pulley O to a post, I, near the other saw Q. These saws are arranged on opposite sides of the platform, and are intended to have independent log-holdin g apparatus for each; and they are worked independently, one being connected to shaft E by the slide or cross-head It, connecting-rod T, and disk U, the latter having a crank-pin for operating said connecting-rod and slides, and the other is similarly connected to shaft F by the slide V, rod W, and disk X. The ways for the said cross-heads are cased'over, as shown at Y, to protect them and the horses, whose path crosses them. The shaft G is to drive a large pulley, Z, from which to belt off,

for driving a circular saw for cutting up small 7 limbs while the larger portions of the trunks are being cut by the long saws. This pulley may also be utilized for driving thrashingmachines and other machinery of any kind for which the power may be adapted.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The combination of the driving-wheel A, two saws with independent connecting and operating gears, the shifting-levers I, and connecting-cord, substantially as specified.
